The particle size can be controlled by regulating the blowing rate of the inert gas, ultrasonic oscillation and soln. viscosity at this time. The noble metal particles of arbitrary sizes having the less fluctuations in the particle size are thus obtd.

IPC: H02M3/155
Filed: 1993-07-28
Abstract: PURPOSE: To contemplate improvement of a power supply circuit and reduction of noise by that the state of a high switching current reduces the switching frequency in connection. CONSTITUTION: The oscillated frequency of an oscillating circuit is modulated as the function of the instant value of rectified AC voltage by the frequency modulating circuit constituted of a divider circuit D.

Accordingly, the oscillatory frequency is variable, and besides it is inversely proportional to the instant value of the rectified AC voltage being standardized concerning the RMS value.

Abstract: PURPOSE:To improve the extent of guide accuracy for a slider by constituting an oil passage device with a slender feed oil groove in the slider moving direction, a first oil feed passage interconnecting this oil feed groove to each hydrostatic pocket and a second oil feed passage to be opened to a guide way being interconnected to the oil feed groove all the time. CONSTITUTION:Lubricating oil fed to a second oil feed passage 33 is led into an oil feed groove 31 even if a slider 20 exists in any position of its sliding stroke, then it is led into each hydrostatic pocket 22 by way of a first oil feed passage 32 and a throttle member 35, supporting the slider 20 slidably on a guide member 10, and it is discharged to the outside through a clearance between a sliding surface 21 around each hydrostatic pocket and a guide way 11. Consequently, there is unnecessary to connect a flexible oil hose or the like to the slider 20 for that not only the slider 20 is hydrostatically supported on the guide member 10 but also pressurized lubricating oil is led into the hydrostatic pocket. Accordingly, any external force is in no case added to the slider 20, thus guide accuracy for the slider is improvable.
